Diagrammatic Reasoning as the Basis for Developing Concepts: A Semiotic Analysis of Students' Learning about Statistical Distribution

In recent years, semiotics has become an innovative theoretical framework in mathematics education. The purpose of this article is to show that semiotics can be used to explain learning as a process of experimenting with and communicating about one's own representations (in particular ‘diagrams') of mathematical problems. As a paradigmatic example, we apply a Peircean semiotic framework to answer the question of how students develop a notion of ‘distribution' in a statistics course by ‘diagrammatic reasoning' and by forming ‘hypostatic abstractions', that is by forming new mathematical objects which can be used as means for communication and further reasoning. Peirce's semiotic terminology is used as an alternative to concepts such as modeling, symbolizing, and reification. We will show that it is a precise instrument of analysis with regard to the complexity of learning and communicating in mathematics classrooms.

Statistical Reasoning in Psychometric Models and Educational Measurement

This paper explores three points raised by Divgi (1986) in order to explicate the important distinction between deterministic and statistical reasoning in the application of statistical models to educational measurement. The three issues concern the relationship between data and esimation equations, the distinction between parameters and parameter estimates, and the power of tests of fit of responses across the ability continuum.

Development of the Statistical Reasoning in Biology Concept Inventory (SRBCI)

We followed established best practices in concept inventory design and developed a 12-item inventory to assess student ability in statistical reasoning in biology (Statistical Reasoning in Biology Concept Inventory [SRBCI]). It is important to assess student thinking in this conceptual area, because it is a fundamental requirement of being statistically literate and associated skills are needed in almost all walks of life. Despite this, previous work shows that non–expert-like thinking in statistical reasoning is common, even after instruction. As science educators, our goal should be to move students along a novice-to-expert spectrum, which could be achieved with growing experience in statistical reasoning. We used item response theory analyses (the one-parameter Rasch model and associated analyses) to assess responses gathered from biology students in two populations at a large research university in Canada in order to test SRBCI’s robustness and sensitivity in capturing useful data relating to the students’ conceptual ability in statistical reasoning. Our analyses indicated that SRBCI is a unidimensional construct, with items that vary widely in difficulty and provide useful information about such student ability. SRBCI should be useful as a diagnostic tool in a variety of biology settings and as a means of measuring the success of teaching interventions designed to improve statistical reasoning skills.

《广韵》各声类字的一个统计分析

文章首先对《广韵》中17537个字在调类、开合和等第的分布情况作了统计．其次对各个声类的出现频率、它们与开舍口以及与各个等的配合情况作了统计。统计结果显示各个声类的分布是不平衡的。它们与开合口和各个等的配合也具有倾向性。本文对这种分布不平衡的原因作了初步探讨。     

搭配词量化分析的统计学原理

搭配词统计分析方面的文献不乏对具体方法和计算公式的陈述,但是对于其统计原理的解释并不充分,具体包括如下一些重要问题:词汇统计研究中总体与样本的概念、搭配词统计分析的基本模式、词频分布与词语概率、词汇统计研究中的假设检验原理.本文综合相关文献中的理论、结合统计学理论,对现有文献进行总结和补充,为常用的搭配词统计分析原理构建一个简单明了的解释体系.     

基于全面小康收入的统计分析

通过2006-2012年全国统计年鉴中可支配收入、总收入、工资性收入、经营性收入、财产性收入和转移性收入数据分析,判断出收入差距状况,将收入划分为高、中高、中等、中低、低五类,利用模糊C均值聚类方法,将所给数据中每一年的收入划分为以上五类,运用Matlab软件进行聚类分析,运用Excel软件对数据分析处理,利用最小二乘法,拟合出洛伦兹曲线函数,对2012年我国的统计年鉴中的数据进行分析、筛选并整理,建立了人均收入模型,使用Excel统计目标数据,并根据国家提出的小康水平指标标准,将目标数据和标准指标值进行比较,得出我国目前所达到的小康水平状况。
